'nited States GEORGE F. JOYCE, OF BOSTON, MASSACHUSETTS.

.Letters Patent No. 102,827, lated May 10, 1870.

The Schedule referred to in these Letters Patent and making part of the seme.

To all persons to whom. these presents may come:

Be it known that I, GEORGE F. J oven, of Boston, of the county of Snolk and State of Massachusetts, have invented a new and useful Window-Sash Supporter; and do hereby' declare the saule to he de- .My improvement or invention consists in the combination ot' a button and a slotted plate, or their equiv` alent, with a window-frameand sashes and a band and a clamp applied thereto, to operate as hereinafter explained, the purpose of the said button and slotted plate being, also, hereinafter set forth.

Also, in the combination and arrangement of a ring and stud with the button and slotted plate, and the band'applied to the window-frame and its two sashes, as hereinafter set forth. v

A denotes the frame, and B and C the two sashes, the whole being applied together, so as to-enable each sash to be moved or slid from the top to the bottom ofthe window opening of the frame.

On the toy of the frame A, I fix a support-piece, D, carrying a wheel, E, the latter being free to ,revolve in the support-piece.

'Going around the upper half of the periphery of the wheel, and extending down through slots a a in the window-frame, is a belt or band, F, having one extremity aixed to the upper bar of the upper sash,

and the other to a ring, G, hitched upona stud, H, f

`projecting from the lowerbar of the lower sash, The said ring carries a button, I;

two sashes, as specified.

A lever-elamp, K, pivoted to ears d d, projectingfrom the upper bar of the lower sash, is to operate with the band F, such hand being carried down hef tween such clamp and the sash.

Below thc stud H there is fixed to the window-silt a plate, L, having a slot, e, made through it, such slot being formed as shown in the drawings. plate there is a chamber, f, made in the sill. is designed to receive the head of the button I, which, after having been passed through the wider part of the slot and into the chamber f, and under the narrower part of' the slot, serves to fasten the band to the window-Sill.

On casting the ring off the stud the upper Sash may be lowered, and, by means of the band and the clamplever, may he held suspended at any desirable elevation, or the lower sash may be raised and the upper` sash be depressed, and both he held suspended at such elevations or in such positions as may be desirable.v

By passing the button into the narrower partof the slot, and hit/:hing the ring upon the stud, the lower sash will not only be locked down by such ring and stud, but the upper one will beheld up by them and the band.

I claim- The combination of the button I andthe slotted plate L,A or their equivalent, with Vthe window-frame and sashes, and the band F and clamp K applied thereto, essentially as hereiubefore explained.

Also, the combination and arrangement of the ring G and stud H with the button I, the slotted plate 1.,.

and the band F,applied to the window-flame and its eno. F. JOYCE.
